Residual paramagnetism in silver(III) metalloporphyrin complexes

Abstract

Silver(III) metalloporphyrin complexes, Ag^IIIP [where P = octaethylporphyrin (1), meso-tetraphenylporphyrin (2), meso-tetra(2,4,6-trimethoxyphenyl)porphyrin (3)] were unexpectedly found to contain residual paramagnetism owing to the presence of Ag^IIP in small amounts; the possibility of generating molecular conductors and semiconductors, based on silver metalloporphyrin complexes, is examined.
